The source of morality is observation and reasoning.

The source of morality is observation and reasoning.

We, as human beings use reason all the time. For example my mother tells me not to write on the walls with a marker. I do it several times and she always screams at me. So then, i reason that I don't have to it anymore because my mom told me not to. We also use the observation skills to assume thing around us. For example, we observe that no one is naked walking around so we use clothing just like everyone else. Both observation and reasoning are linked together because through observation comes reasoning. 

Our morals depend on what we see in our family, our culture, our friends, the TV, and other ways of communication. We see what others do and reason if it is a good decision, action, motive or not. For example if in my family I saw that they were against killing, I will reason that I don't have to kill (or if i see someone being sentenced to 35 years in jail because he/she killed someone). And if in my house I see my dad raping my mother, i will deduce that raping is okay, and do it.

It all comes down to education. Morals in the end depend on what you learn through observation and reasoning. Children should have a stronger base (look into their learning not only in school) if society really expects them to be "great" adults...
